In the app there are all the GPX tracks of the PNALM trails, they can be followed using the GPS of the smartphone on a detailed 1: 25000 offline map. You choose the path to follow and the trace in green color appears on the cartography, your path is recorded with a blue trace that overlaps the green one, in this way it is possible to check if the path is the correct one. There is also a waypoints management and you can send the recorded route in GPX format to any email address.The tracks were created and verified by Roberto Bezzu of CAI in Sulmona
